Surge protectors

There are a lot of sources that claim surge protectors can't protect from a lightning because there simply is too much current and the only way to effectively protect any device is to unplug it during storms. On the other hand, several manufacturers say that their protectors, when overloaded, will get damaged themselves but will cut the power to the devices and so it's effectively the same as unplugging them. And there is also the odd anecdotal report of people who say that after a lightning they lost many sensitive devices but those plugged in a surge protector survived. So what's the deal ? Is it possible to 100% protect from a lightning with a surge protector ?
